It’s that day of the week! No, not shower day (some weeks I skip that one). It’s

What to Watch Wednesday

And this week you should watch Moon, in which Sam Rockwell and Kevin Spacey steal the show from…themselves? One of the coolest things about Moon is that there’s only one actor on screen for the entire 97 minutes. Sam Rockwell plays a lonely man on the moon stuck doing a 3-year stint maintaining a nearly automated mining facility. His only companion is an understated robot voiced by Kevin Spacey.

Being alone on the moon is a dull existence, that is, until you stumble upon the injured body of…well, you should just go watch the movie. Everything is not as it seems, and Sam Rockwell must forget the life he thought he knew in order to accomplish something important with what time he has left.

And if it stars Sam Rockwell, you know it’s going to be good. He might be the actor with the best quality to fame ratio. He’s Guy Fleegman in Galaxy Quest: “I’m not even supposed to be here. I’m just ‘Crewman Number Six.’ I’m expendable. I’m the guy in the episode who dies to prove how serious the situation is. I’ve gotta get outta here!” And he’s Justin Hammer, that slick, evil guy from Iron Man 2 who almost outshined Robert Downey Jr. in their scenes together.

If you want a low-budget, high-concept film that will keep you interested and make you think, all the while forcing you to question your concepts of morality, then this is the movie for you. On the other hand, it’s mostly slow and dialogue driven, so if you’re in the mood for something more fast-paced with action, plot twists, and, well, character interaction, then steer clear of this one.
